Questionable Status Register
The questionable status register monitors the instrument's condition to
see if anything questionable has happened to it. It is looking for
anything that might cause an error or a bad measurement like a
hardware problem, an out of calibration situation, or a unusual signal.
All the bits are summary bits from lower-level event registers.
